High-density tungsten alloy shielding components offer significant advantages over traditional lead-based shielding components in practical applications.
Higher Shielding Efficiency: The density of high-density tungsten alloys ranges from 16.5 to 18.75 g/cm3, far exceeding lead’s 11.34 g/cm3. Generally, the effectiveness of ray shielding is positively correlated with material density. At the same thickness, tungsten alloy shielding components provide stronger attenuation of X-rays and gamma rays, meaning that with reduced material usage, their protective effect can match that of lead shielding components.
Superior Environmental Friendliness: Lead is a toxic heavy metal that can cause soil and water pollution through prolonged exposure or improper disposal, requiring strict compliance for recycling and handling. In contrast, high-density tungsten alloys are non-toxic, releasing no harmful substances after disposal, aligning with modern environmental regulations and reducing health risks to operators.
More Reliable Mechanical Properties: Lead is soft and prone to deformation, easily developing cracks or damage after prolonged use or external impact, which can compromise its shielding effectiveness. High-density tungsten alloys, however, boast high hardness and strength, excellent impact resistance, and wear resistance, maintaining structural integrity over the long term, extending service life, and reducing maintenance and replacement frequency.
Greater Processing Adaptability: High-density tungsten alloys can be processed into complex shapes such as curved or irregularly shaped shielding components, meeting the dimensional precision requirements of medical equipment and nuclear instruments. Lead, on the other hand, has lower processing precision, making it difficult to form complex structures and ill-suited for high-precision equipment.
Higher Cost: While the cost of tungsten alloy materials exceeds that of lead, considering their longer service life and environmental compliance (avoiding the high environmental costs associated with lead handling), the overall long-term cost is lower. This makes them particularly suitable for fields with high demands for safety and durability.
In summary, the application advantages of high-density tungsten alloy shielding components include high shielding efficiency, superior environmental friendliness, reliable mechanical properties, and greater processing adaptability.
